Be ithnown that I, EJHQLA'SIIDEOI T, of-Boston, in the county of Snfi'olk, and State of. Mnesechnsett's, heve inventeda new "and useful Improvement-inlflechines or A pparntds for-Drying Various Articles; anddo. hereby 'declare'the following to be a full, clear,' and exact description thereof, dnere'fer'encebeing bed to lib-6 50061111 'panyingdrawings, making part of this spcciiicstion,1nnd.in which'- Figure]. is a; top view of the invention. Figure 2, a top view, with the miter-tank removed. v Figure 3, a vertical and longitudinal section; and Figure an endwiew ot the enidinvention. .t 1 This invention is an improvement in machinesflfor'drying various articles, chieflywool, and reletestd means I for extinguishing fire which-mcy accidentally tcke' plaee in such mnchine front spcntaneonsconibnstion of sub. stances contained therein, or from ignition of its contents from any cause; I i v V .The invention consists in combining with such machine a. tankof water, and connected therewith in .euch .,manner that upon taklggifire of the contents of the machine from any accidental cause, ancpening sl nll' be, created for the-passage of tbe waterte'the interior of the machine, for-the purpose-oi flooding snch interior: and itscontents, in manner and to operate as hereinnfter expleined. v v

In the drawings ebove mentioned as accouipnnying this specification, and: illustrnting' my invention,--A denotes 5.;blower, or air-forcing engine, of "any suitablecgnstructicn, suchblciver bcing'ccnnected by a. corn duit,' 3, with an. aii' receiver erichamber C, such ninchainberconstituting the lower part efn rectangulalnroom. orstructure, D, the iloor, E,-of \v hich is "lflmllflllfl orprovided with a plin'alliy of ehort upright piPes ,'-a. l,, &c., for passage of-air to the interior of such structure from the'blow'er or eismhnm eer.

Theinteriorjof thestr-uctnre D is provided with a .ooiled, .zigdag,lor.serpentine steam-pipe, F, the jnie t 'end outlet of which is outside ofthe structure, the purpose'ef this'ste'nm-pipe being to heat the interior of the struc. tare end the blast of air'iiessing npwnrd'thronghitfrom Ttheeir-channben I A,-f craminous floor, G, isdisposed across the upprfpert of the striictnre D, and surmounting, the'ste'a m pipe, such floor being fcr-receptinn of the' wool; 0! other mnt e'iialto be dried.

Atank; H,, is'.disp0sed above the structi rre?D, vand is provided with an erificeer valve-opening, 'L for permittingflowjof water contained itithetank tethefinteriorof 'th-estructure below, sdcli orifice being closed at ordinerytiines by n valve, 11; this valve being secured to the Towel-end pforvmaking part of right-nng'n'lar rod, .9, such' rod being fulcrumed, as shown at (Lat nbout the-middle of its liorizen tu'l'portion, to a. post, d,- extending -upivnrdfrom one side of the tank, the outer extremity of suchrod being "pivoted to the upper end of e second bent rod, e,' which extends from the'rod c to thein'tericr of the strncture D, the lower end of ethe last inentioned rod resting upon Sand being upheld-13y p. fusible plug, f, confided within a pipe, 9, or recessed post, which is fixed. to the floor of the structure in a. suitable'tuanner; the neightof the 'ro'd-e' being suficient fo meie than countervb n lattice the weight offthe rod c-nnjl its valve 6'. The 'plug f is tomelt at it ten pei'atui'e of. 21 2 Fnhrenheit.

- The-cperation of the ubcvedescribcd. arrangement. (if-parts. is 'nsffollon'vs; i t' b'eing'nnderstoed that a. mass of wool; or other material to be dried; is placed uppn the 'i'citamincus 'tloor 'G, of the structure, and mblem: of air impinging against andsurroundingit; us will be" ovidenltfrorn the description before given:

Should'fire nccidentnlly take piece within th e structure;by'lneansiefispontaneous conibnstion frem'oily matter, or o'therrefuse from themut'eiial tojhedrieqer frofin any'cnuse, the heet induced by such fire will melt the fnsiblelpl ng'f, beforementien ed a sisuiipoirin th'e rod'c, and 'unee'n full of slichreil I This falling of the rode will so a'etnete the'i'odor lever c .as tor'aise thevalveeend'nllowthefwnter-cen tai'ried in-the tank to flow thfoug-h the orifice I. into, the's tructureg, an .l pref'ercblythicugh n p'erfoi'a'te d' do n.

or shelf, 13, disposed be'levr theifio'or of thenn tcr-tanli,ins-shown in the accompanying drawings. "The efijectlef theinlling water will here immediately and cutomutieclly extinguish any fire withinthe structure,- as v'rill readily manifest itself to intelligent persons;

The employment of the perforated floor 72, causes the water. to be discherged into the eteucture in a. fine spray, which is eminently calculated-f0 produce the desired effect. v i

I Wplild remark that in place-of the fusible plug and the two rods 0 and e, arranged as before described, for

operating the va-liie 6, I have contemplated supporting the valvezupon epost'fixed to the floor of the structure,

and dlsposin'gbelow'snch valve an expnnsible pipe or rod,' o'f such material ind of such length, that the heat impar-tedfrom 'tbe fire-within the sttu'ctureshall lengthen the expensibl'e pipe or red and by raising the valve, open the orifice I to-"the flow of the wateri' The deviceabove mentioned 'constitu'tes' en automatic safety-gnardagaihet destruction, by-aceidental fire, of wool-drying machines, whichhow frequentlytek es placeby reason ofs'pcntaneous combustion of inflemmable substances which acc'umnlete, to o, greater qrless extent, in the process of drying'tbewopl.

I claim, in combination with a. machine for drying various materials or substances, a tank of wnter,wh)'n the'discharg'e of water from such tank is eflected by the action of fire accidentally teking'placeint'euch machine, for the pin-pose substantially as before described. I

.I also claim operating the valve "and opening the dischargingwrifie'e of'the watehtank, or of regulatingthe flew of water 'to the strnctnre by means ofpa' fusible plug connected therewith by any suitable means which.

accomplish the desired resnltr': I

I also claim the combination and arrangement, with the structureD and water-tank H,'Of the'discharging;

orifice I, valve 6, rods 0 and e, a.nd fusible plug-f, the whole being combined, arranged nd operating as before,

described.

I also claim a rod-p pe, or itsfeqnival ent, combined with the discharging-critical end iiclve b, in such manner that dponexpansion offencb. rod, or its-equivalent, by reason of fire Within the structure, the valve shall recede from and open'j the orifice to the discharge of water" to the structure; essentially as hereinbefore described. I

I -also claim. the general combination and {arrangement of the blower A, eir-chember G;- with the structure D, and its perforatedor fcreminous floors E and-G, land steam-coilor pipe F, the wa ter-tank H, and the appn rates fax; discharging water therefrom, the whole'being arranged and opei'cting g substantially es hereinbefore described.
